It was reported that the procedure was to treat a moderately calcified lesion in the superficial femoral artery (sfa).Pre-dilatation was performed with an unspecified balloon dilatation catheter (bdc).The 6.5mmx120mmx120cm supera self-expanding stent system (sess) was advanced to the target lesion without issue; however, during deployment the stent implant could not be fully deployed.Reportedly, there was no issue with the handle or locks of the sess.Multiple attempts were made to fully deploy the stent implant; however, the proximal portion of the stent did not release.During the attempt to remove the sess delivery catheter, the stent implant was pulled/migrated completely out of the target lesion and into healthy tissue.An absolute pro stent implant was deployed to treat the target lesion.There was no reported adverse patient sequela and no reported clinically significant delay in the procedure.There was no additional information provided.
